They are all the rage right now, they help you find your family's history. "We've always wondered about the validity of my dad's side of the family and their claims about where we're from."Elizabeth Makos is as curious as we all are. "So we think we are half Italian, quarter Czechoslovakian and a quarter polish."She agreed to help put these DNA tests, to the test. Makos gave saliva samples three times, one for Ancestry DNA, 23 and Me and MyHeritage. We sealed them up and sent them off and waited about 6 weeks.We got her results back and here's what Makos thought of them."It's shocking. It is really shocking. I can't imagine what technology they employ to get these results," she said.It's shocking because her results were all over the place. When it comes to Eastern Europe, Ancestry said she was 49 percent Eastern European, but 23 and me and MyHeritage only put the percentage in the high 20s. "When we look at it for example, it says the Balkans here… one says 34 percent and one says 18 percent. A bit of a discrepancy there."Makos thought for sure she is 50 percent Italian. 23 and me and MyHeritage says she's closer to 30 percent. She even had some North African DNA."I would love to know," Makos said about having North African DNA. "I know I get really tan in the summer but I didn't know I got that tan… who knows."The companies don't claim to be perfectly accurate, and use different algorithms. MyHeritage told us in a Skype interview, it maps more parts of the globe that other companies."MyHeritage DNA has 42 ethnic regions with percentages and that's the most on the market, Rafi Mendelsohn, spokesperson for MyHeritage said."Mendelsohn encourages you to read the fine print including what companies might do with your DNA profile after testing."Personal information provided to MyHeritage is never sold, licensed or shared with any third parties, he said." Both Ancestry DNA and 23 and Me say your DNA could be used for medical research by its "partners" after your name has been stripped out. Peter Pitts, a former FDA associate commissioner said, watch out."Companies will tell you that they may sell the information but nobody can find you," Pitts said. "And that's not true. There's been studies done at Harvard for example where a couple of professors got genetic information that was supposedly anonymous and was able to figure out who the people were through very easy mechanisms."He says the results shouldn't be taken as gospel and companies say don't use the findings to make medical decisions. "People need to understand that what they're getting back is an interesting snapshot not necessarily accurate or clinically relevant," Pitts said. Makos said she's telling her friends to use the tests only for fun."I'm glad we did this because I probably would have just taken one test on my own and completely trusted the results. This was very eye opening for sure." 2972

Those in the United States on a student visa could be booted from the country this fall if they are not attending in-person classes, the US Immigration and Customers Enforcement agency announced Monday.At universities that are planning on going online only, students will need to transfer to a university with in-person classes or face being deported from the US. This also means at universities where students have the choice between online and in-person courses, they will need to mostly take in-person courses. This could be an issue for students considered at a high risk of developing complications from the coronavirus. Amid the coronavirus, most universities have stated plans to resume in the fall with in-person courses. But with cases surging around the country brings uncertainty on whether universities will be able to conduct in-person classes.On Monday, Harvard announced plans to hold online courses with limited in-person services. Harvard’s plan will allow for freshmen to live on campus while the rest of the university will mostly be kept away from Harvard.“Harvard was built for connection, not isolation. Without a vaccine or effective clinical treatments for the virus, we know that no choice that reopens the campus is without risk,” the president and deans wrote. “That said, we have worked closely with leading epidemiologists and medical experts to define an approach that we believe will protect the health and safety of our community, while also protecting our academic enterprise and providing students with the conditions they need to be successful academically.”Princeton also announced Monday that most of its courses will be held online. Princeton said it would work with international students who might not be allowed to enter the US due to visa restrictions.“For undergraduates living abroad who are unable to return to campus, there will be some limitations on which courses are available to students who are not in residence,” Princeton said in a press release. Acknowledging time zone and other limitations unique to those living overseas, faculty members and administrators will make every effort to ensure that students studying from abroad will be able to participate in the virtual curricular and co-curricular aspects of the Princeton experience.” 2299

TIJUANA, Mexico (AP) — More buses of exhausted people in a caravan of Central American asylum seekers reached the U.S. border Thursday as the city of Tijuana converted a municipal gymnasium into a temporary shelter and the migrants came to grips with the reality that they will be on the Mexican side of the frontier for an extended stay.With U.S. border inspectors at the main crossing into San Diego processing only about 100 asylum claims a day, it could take weeks if not months to process the thousands in the caravan that departed from San Pedro Sula, Honduras, more than a month ago.Tijuana's robust network of shelters was already stretched to the limit, having squeezed in double their capacity or more as families slept on the floor on mats, forcing the city to open the gymnasium for up to 360 people on Wednesday. A gated outdoor courtyard can accommodate hundreds more.The city's thriving factories are always looking for workers, and several thousand Haitian migrants who were turned away at the U.S. border have found jobs and settled here in the last two years, but the prospect of thousands more destitute Central Americans has posed new challenges.Delia Avila, director of Tijuana's family services department, who is helping spearhead the city's response, said migrants who can arrange legal status in Mexico are welcome to stay."Tijuana is a land of migrants. Tijuana is a land that has known what it is to embrace thousands of co-nationals and also people from other countries," Avila said.Mexican law enforcement was out in force in a city that is suffering an all-time-high homicide rate. A group of about 50 migrants, mostly women and children, walked through downtown streets Thursday from the city shelter to a breakfast hall under police escort.As buses from western and central Mexico trickled in overnight and into the morning, families camped inside the bus terminal and waited for word on where they could find a safe place to sleep. One shelter designed for 45 women and children was housing 100; another designed for 100 had nearly 200.Many endured the evening chill to sleep at an oceanfront park with a view of San Diego office towers and heavily armed U.S. Border Patrol agents on the other side of a steel-bollard fence.Oscar Zapata, 31, reached the Tijuana bus station at 2 a.m. from Guadalajara with his wife and their three children, ages 4, 5 and 12, and headed to the breakfast hall, where migrants were served free beef and potatoes.Back home in La Ceiba, Honduras, he had been selling pirated CDs and DVDs in the street when two gangs demanded "protection" money; he had already seen a colleague gunned down on a street corner because he couldn't pay. He said gangs called him and his wife on their cellphones and showed up at their house, threatening to kidnap his daughter and force her into prostitution if he didn't pay.When he heard about the caravan on the TV news last month, he didn't think twice."It was the opportunity to get out," Zapata said, waiting in line for breakfast.Zapata said he hopes to join a brother in Los Angeles but has not yet decided on his next move. Like many others, he planned to wait in Tijuana for others in the caravan to arrive and gather more information before seeking asylum in the United States.Byron Jose Blandino, a 27-year-old bricklayer from Nicaragua who slept in the converted gymnasium, said he wanted to request asylum but not until he could speak with someone well-versed in U.S. law and asylum procedures."The first thing is to wait," Blandino said. "I do not want to break the laws of any country. If I could enter in a peaceful manner, that would be good.To claim asylum in San Diego, migrants enter their names in a tattered notebook held together by duct tape and managed by the migrants in a plaza outside the entry to the main border crossing.On Thursday, migrants who registered six weeks ago were getting their names called. The waiting list has grown to more than 3,000 names and stands to become much longer with the caravans.Tijuana officials said there were about 800 migrants from the caravan in the city Wednesday. The latest arrivals appeared to push the total above 1,000.The migrants have met some resistance from local residents, about 100 of whom confronted a similar-size group of Central Americans who were camped out by the U.S. border fence Wednesday night."You're not welcome" and "Get out!" the locals said, marching up to the group.Police kept the two sides apart.Vladimir Cruz, a migrant from El Salvador, shook his head and said: "These people are the racists, because 95 percent of people here support us.""It is just this little group. ... They are uncomfortable because we're here," Cruz said.Playas de Tijuana, as the area is known, is an upper-middle-class enclave, and residents appeared worried about crime and sanitation. One protester shouted, "This isn't about discrimination, it is about safety!"There are real questions about how the city of more than 1.6 million will manage to handle the migrant caravans working their way through Mexico, which may total 10,000 people in all."No city in the world is prepared to receive this number of migrants," said Tijuana social development director Mario Osuna, adding that the city hopes Mexico's federal government "will start legalizing these people immediately" so they can get jobs and earn a living.Dozens of gay and transgender migrants in the caravan were already lining up Thursday to submit asylum claims, though it was unclear how soon they would be able to do so.The caravan has fragmented somewhat in recent days in a final push to the border, with some migrants moving rapidly in buses and others falling behind.On Thursday, hundreds were stranded for most of the day at a gas station in Navojoa, some 750 miles (1,200 kilometers) from Tijuana."We were dropped here at midnight ... in the middle of nowhere, where supposedly some buses were going to come pick us up, but nothing," Alejandra Grisel Rodriguez of Honduras told The Associated Press by phone. "We are without water, without food."After about 12 hours seven buses began arriving to collect the migrants, Rodriguez said, but they quickly filled up."We would need at least 40 or 50," she said.Jesus Edmundo Valdez, coordinator of firefighters and civil defense in Navojoa, said Wednesday that authorities were providing food, water and medical attention to migrants there. His phone rang unanswered Thursday.Mexico has offered refuge, asylum and work visas to the migrants, and its government said this week that 2,697 temporary visas had been issued to individuals and families to cover them during the 45-day application process for more permanent status. Some 533 migrants had requested a voluntary return to their countries, the government said.___Associated Press writer Maria Verza contributed from Culiacan, Mexico. 6880

Theater chain AMC says it could run out of money by the end of the year, according to multiple reports.AMC Theatres said Tuesday that its existing cash resources would be "largely depleted" by the end of this year or early next year because of the "reduced movie slate for the fourth quarter," as well as "the absence of significant increases in attendance from current levels."The company says they either need to sell more tickets or find new ways to borrow money.AMC has about 500 of their 600 American theaters open at between 20-40 percent capacity depending on local regulations to stop the spread of the coronavirus.Cineworld Group, which owns Regal Cinemas, announced last week it would suspend operations at all theaters in the US and UK.Meanwhile, the film industry has pushed release dates or gone straight to streaming platforms as the pandemic continues to disrupt theater attendance and filming schedules.Marvel’s “Black Widow” and the latest James Bond film “No Time to Die” were pushed to 2021. Pixar’s “Soul” will not appear in theaters and will go straight to Disney+, like Disney’s live-action remake of “Mulan.”There are only a few new films still slated for a 2020 release, including Universal’s “The Croods: A New Age,” Disney’s “Free Guy,” Paramount Pictures’ “Coming 2 America” and Warner Bros.′ “Wonder Woman 1984.” 1348
